美国杜邦科慕特氟龙铁氟龙涂料涂料粉末NEOFLONTM PFA涂料粉末

NEOFLON PFA涂料粉末是四氟乙烯和全氟烷基乙烯基醚共聚物的细颗粒。

由于NEOFLON PFA的熔体粘度低于POLYFLON PTFE，因此可以制成无针孔涂膜。 它适用于防腐衬里。

该薄膜具有与POLYFLON PTFE薄膜相同的优异性能，如耐化学性，耐热性，不粘性，低摩擦性和出色的电性能。

Coating powderNEOFLONTM PFA Coating Powder

NEOFLON PFA coating powder is fine particles of copolymer of tetrafluoroethylene and perfluoroalkylvinylether.

Since NEOFLON PFA has lower melt viscosity than POLYFLON PTFE, it can make a pinhole-free coating film. It is suitable for anti-corrosion linings.

This film shows the same excellent properties of POLYFLON PTFE film, such as chemical resistance, heat resistance, non-stick property, low friction and outstanding electric property.

3-1 Characteristics of the powder

3-2 Characteristics of the coating film

* 1) A steel substrate was roughened by sandblasting.
2) TC-11000 was applied as a primer.
3) NEOFLON PFA coating powder was applied into 500μm thickness. 4) The film was peeled toward 90° against substrate.

4. Processing

4-1 Coating

NEOFLON coating powder can be applied with using the same equipment as general powder coatings, such as electrostatic coating and rotational molding.

(1) Procedure of NEOFLON powder coating [For electrostatic coating]

Finish the corner parts between 3 and 10R and eliminate pinholes at parts of the welding finish.

Remove stains such as oil and grease on the surface of the base material

Sandblast

Primer layer : 80~90°C×10min or more

Electrostatic coating

Water, air, and furnace cooling are applicable.

4-2 Procedure of NEOFLON powder coating [For rotational molding]

In case of lining, apply a primer instead of a releasing agent.

5. Handling instructions

1. (1)  Please wear glasses, gloves, and masks while handling agents.

2. (2)  During sintering powders, or at sites places where the resin temperature is high (PTFE,

PFA=260°C, FEP=205°C, ETFE=150°C), please ensure good ventilation as well as installing local ventilation equipment. In case any person inhales fumes generated during sintering, this may result in polymer fume fever, which has symptoms similar to a cold. Please control to ensure the temperature of the resin does not exceed a high level (PTFE, PFA=380°C, FEP=360°C, ETFE=310°C) during sintering. If the temperature rises excessively, thermal cracking will increase, which may generate hydrogen fluoride.

3. (3)  Please avoid smoking at the work site as you may inhale hazardous gases if smoking a cigarette coated in NEOFLON coating powder. Wash your face and hands after processing work to ensure any cigarette is not exposed to the powder coating.

4. (4)  If you dispose of NEOFLON coating powder, avoid discarding into the sewage, and store in

a specific container for disposal. For this purpose, make consignment contact with an industrial waste management company in order to consign the disposal.
